To all whom it may concern.-

Be it known that I, MARo V. PALMER, of Willimantic, in the county of Windham and State of Connecticut, have invented certain new and useful Improvements in Machines for \Vinding Cops for Sewing-Machine Shuttles, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my inventionis to provide a machine by means of which a peculiar cop may tripdevice and of the adjusting device.

be wound compactly and evenly to adapt itfor use in the shuttle of a sewingmachine.

To this end my improvement consists in the combination of devices whereby the cop is wound between the faces of rollers running at substantially the same velocity.

It further consists in the combination of the spring-seated bearingsthat' support the pin on which the cop is wound under pressure be tween the rollers.

It further consists in the stop device, in the adjusting device that determines the diameter of the cop, in the combination of devices for pulling out the pin, and in further details of the parts and their combination, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure 1 is a front View of one of my improved machines for winding shuttle-cops. Fig. 2 is a top view of the same. Fig. 3 is'a detail top view of the Fig. 4 is a View in vertical crosssection of the device on plane denoted by line 00 00 of Fig. 1. Fig. 5 is a detail view in vertical section of the machine on the same plane, showing the parts in position after tripping the upper roller. Fig. 6 is a detail top view of the device for pulling the pin out of the cop.

In the accompanying drawings, the letter A denotes the frame or bed of the machine. b and 1) denote standards; a, the main shaft extending across the machine and supported in bearings in the standards; d, a pulley to receive a belt, by meansof which the machine may be driven from any convenient countershaft or source of power. Fast to this main shaft 0 is a cam-block, 6, having a cam-groove, e, into which projects a pin, f, borne on a block, ffladjustablysecured to the sliding rod f, as by means of a clamp-screw, f On this reciprocating rod are supported the guides 9, through which the thread passes while being wound to form a cop.

The device just described is the ordinary traverse device common. to other winding-machines, and the guides are also of wellknown construction.

The thread passes to the guides through the tension device h on the upper end of the arm h, fast to the frame of the machine. On the main shaft 0 there is also fast a cog-wheel, c, meshing into a larger cog-wheel, 0 that is supported on an arbor, 5, held in the standards b b and extending across the frame parallel to the main shaft. The wheel 0 turns freely on this arbor and meshes into a gearwheel, 0 that is fast to the shaft 0 of the roller that is supported in bearings on the outer end of the frame K. This roller-frame is supported by and swings freely on the arbor i, holding the roll it at the lowerlimit of its play directly over the roll 70 that is fast to the same shaft as the cog-wheel c and is driven by it. The arrangement of cog-wheels just described is such that the adjacent faces of the two rolls 7a 7a travel in opposite directions. The front ends of the arms of the spring Z, that is sup.- ported on the standard Z on the back of the frame,lie between the planes of the upper and lower rollers, 70 k and are formed with' the bearings Z for a small pin, m, on which the cop n is wound, and this pin-is held in its bearings directly between the surfaces of the rolls 7c 70.

In Fig. 5 I have shown the rolls and pinbearings in the positions they are caused to assume when it is desired to remove a wound cop or to place a pin within the bearings, the upper roll, 70, being shown held above and out of contact with the cop or pin, which latter is in turn held out of contact with the roll If, these parts occupying the relative positions shown. After removing a wound cop and placing a base-pin in the bearings, by pulling forward upon the handle q, the frame K is so moved as to hold the pin with a yielding pressure upon the lower roll and between the surfaces of thetwo rolls. The upper roller, is, is thrust downward with a yielding pressure upon this pin by means of a spring, 70, that is coiled about the hub of the arm 0, that is also supported on the arbor t. One-end or loop of this spring supports an adj usting-serew, k", by means of which the degree of pressure of the spring upon the frame K may be adjusted, while another loop of thespring passes around the back of the arm 0 in such manner that the tension of the spring tends to rotate the frame and the arm in opposite directions on the arbor z. The lower end of this arm 0 has a slot, 0, through which passes a pin, 0, by means of which it is connected to a slide, 0 moving in guideways across the frame A. In asoeket, a, in the upper part of the frame is seated a spring, 0, with one end fast to the front part of the frame and the other to a hook fast to the slide, the function of the spring being to pull the slide forward. This slide forms part of the trip device P,the function of which is to lift the upper roller, out of contact with the cop n as soon as it has reached the predetermined diameter, and this lifting of the upper roller allows the spring 1 to lift the cop out of contact also with the lower roller and stops the further winding of any thread upon the cop.

The bell erank lever 11 (see Figs. 4 and 5) is U pivotally connected to a stand on the front of the frame,with one arm, extending toward the slide 0, and bearing a roller, 12 adapted to rest against the shoulder or angle 0 on the front of the slide. The upper arm of this bellcrank lever 19 is connected by means of the rod 1) with the dog 1), that is pivoted to the upper part of the bed or frame A, and projects upward,with its outer end arranged to come into contact with the arm k", that projects downward from the hub of the frame K. By means of the adj usting-nuts p the point at which the upper end of the dog and the lower end of the arm it slip past each other may be determined.

In order to return the frame K and the roller 70 to the lower limit of their play, the handle q is pivotally supported 011 the arbor i and is provided with a sidewise-extending arm, q, that by contact with the arm 0, that projects from the hub of the arm 0, causes, when this handle is pulled forward, the arm 0 to be pulled backward, and the tension of the spring 7; forces the frame downward. Another arm, q projecting from the hub of the handle, serves by contact with a post or standard, q, fast to the frame, to limit the backward play of the handle.

The operation of my device is as follows: A pin, at, having been placed in the bearings in the front end of the spring-arm, the roller k is, by the means already described, brought down upon it and held there by the pressure determined by the spring 70*, the pin being held between the adjacent surfaces of the rolls 7; and 7c. The end of the thread is caught on the pin, and by the rotation of the main shaft 0 is wound upon it, the traverse motion of the thread being imparted by the reciproeating motion of the slide-rod and under pressure between the two rolls, so that the thread is massed evenly and closely upon the pin. This winding of the thread upon the pin continues until the cop has reached the desired diameter, and the end of the arm it forces the end of the dog over, tilting the lever and lifting the roller p" out of contact with the shoulder 0' on the slide. The slide is then pulled sharply forward by means of the spring 0, and the upper roller lifted out of contact with the cop and further winding of thread stopped. Thethread is then cut close to the cop and the latter removed from the spring-supported bearings. The pin m,upon which the cop is wound, still remains in it, and to pull it out Imake use of the pullout device R. (Shown in Fig. 6 of the drawings.) A cog-wheel, r, is borne on ashaft, r, mounted in astandard, r, fast to the frame, in such position that the wheel meshes with and is driven by the large gear-wheel 0*. A crankarm on the shaft r is connected by a pitman, T to the leveri", that lies crosswise of the pitman and is supported at one end in a groove in the stand 8, and at the other is pivoted to the front end of the slide r", that lies about parallel to the path of the pitman. On the front end of the slide 1' ajaw, r, is located opposite to the outwardbent end of the lever r,which end forms the complementaryjaw 1- and between these jaws the end of the pin on is grasped at the instant the pitman begins its return movement, its pull on the lever closing the jaws,while the push of the pitman opens the jaws.

One end of the cop is held against the end of the rest t with the end of the pin projecting toward the jaws and adapted to be grasped by them, as described.
